This invention relates to a coin controlled mechanism for vending machines.

Experience in actual operation of vending machines has shown that they get out of order owing to hard usage by the public and that it J is frequently necessary to repair and replace the coin controlled mechanism. Therefore, one object of the invention is to provide an extremely sim le form of construction on one removable plate which may readily be attached to the front ,wall of a vendin machine casin Further experience with vendlng machines has shown that the public will attempt touse improper coins, as well as slugs and wash- Lers. The present invention is intended for use with coins of a non-magnetic character and the broad, general object of the invention is to provide a simple construction which cannot be operated by an improper coin' or by a slugor washer and that when an 1mproper coin, slug or washer is inserted, goods will not be delivered and such coin, slug or washer will be returned.

Experience with vending machines has further shown that when the machine is empty and customers insert-coins the customer becomes exasperated and frequently injuries the machine, so that one of the objects of the invention isl to provide a means for automatically indicating when the machine is empty of oods and for automatically and positively locing the coin insertionopening so that a `coin cannot be inserted when the vending machine is empty of goods.

Experience has furthervshown that owing to hard usage coin controlled mechanisms of thisA type will become jammedorbro'ken. When a coin is inserted under such conditions and not lpeturn'ed, naturally the customer is object of t e invention is to provide a very simple construction, so that the parts are interchangeable and so that the construction may be quickly taken down and reassembled y* with simple tools.

The invention consists of 'the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part hereof, is illustrated one form of embodiment of the invention, in which drawingsy the direction indicated by the arrows;

Disposed in the opening in the wall A is a supporting -panel 12 which carries the entire mechanism hereinafter described. The panel 12 is provided with edge iianges 13. Anl elongated boss 14 isdisposed on .the panel 12 near its top. Between one flange 13 and the boss 1'4 is disposed a rectangular plate rockably l, carried by a pivot-pin 16 which pin 16 extends through thelboss 14 and the flange 13. f

The plate 15 is provided with strengthening ribs'17. The plate 15 also has a recessed portion 18 near the top for the'purpose of receiving and holding an indicating means here.

i-nafter described. Disposed centrally ofthe plate 15, and at the pointwhere the pin 16 passes through, is an opening 19 so that a plate 20 may` be pivoted on the pin 16 between the plate 15 and the panel t12. The plate 2O isprovided withan angularly offset portion 20a on the front facethereof, the use of which is hereinafter described.

. Disposed between the ribs 17 on the plate 15 is a U shaped magnet 21. The ends 22 of the magnet 21 are bent atan angle of 90 and to the forward'face of the plate 20.

pose of themagnet 21 is to catch and hold Yany slug or other improper coin which may be inserted in the machine, as hereinafter (leextend'through openings 23 hi the plate 15 and also through openings 24 in the 'lplate 20 he purscribed. Between the arms of the magnet 21 is a retaining member 25 havingproJ'ecting' flanges in these slots 33 and 34 is allatch 351whichA .is pivoted oflcenter bya ,pin 36 `through the 26 which hold the magnet 21 in position. The retaining member 25 is provided with a recess 27 in which ispla'ced a spiral spring 28.

A stud'29p'asses through the spring 28, tlie 'retaining member 25, the plate 15 and into the second plate 20. Therefore, when the plate 15 .is actuated as hereinafter described, the

springA 28 is compressed and, under tension,l

moves the stud 29 and the plate 20. A pin 30 in oneedge flange 13 of the panel 12 limits the range of -movement of' the plate 20, (Figure`-1) A recess 31 1s provided on the front face of the plate 15 near the topthereof. .A spiral spring 32 is disposed in the recess 31 andewhen v-the plate 15 is actuated the spring 32 is compressed, and tends to return t e plate 15 to its normal position. plate 20 is limited by the pin 30 the spring 28 also exerts pressure on the plate 15, tending to return it to its normal position.

The plate 15- is provided with Va vertical slot 33; and in alignment therewith is a second vertical slot .134 in the plate 20. Disposed shaft 41.

Since the movement of the Lacasse adapted to engage anykind ofapparatus which may beJ operated by/rotation. of the A'circular boss 44 is disposed on the panel forward face of the lever is a lug 47 which is adapted to act as a coin holder. A second lever 48 is also pivoted on the b oss 44 behind the lever 45. .The lever 48 has a vertical 7 flange 49 on `its forward face in alignment with the lug, 47.on the lever 45 so that vwhen a .proper coin is inserted it will be held between'the lug 47 and the flange`49.

J12. An offset lever 45 is pivoted on the boss '70 44 and is provided with a flange 46. On theV Centrally of its' vlength the lever 48 has a 30 shoulder 50.- When themechanism is .in normal position theshouldery 50 lies in the path of movement of atrecess 5,1 on the collar 40 on the shaftf41 so that thehandle 42 may be turned lapproximately 20 before 8 the shoulder 50 engages the recess 51 and prevents furt-her movement. When in this position the lever 45 is against the thinnest part of the eccentric collar 40.'

The levers .45 and 48 `are held against the 9 'collar 40 by means of a leaf spring 5.2 which is inserted between the levers 45 and 48 and4 one edge flange l13 -on'the 'panel 12. The upper end 53 of the spring v52 engages ajlug 54 on the lever 45 and the lower end 55 of 9 the spring 52jengages yin a recess 56 in the lever 48,;thusho1ding both thelevers 45 and 48 yieldingly against the collar 40. The lever 45 is `in contact with the forwardportion ofthe collar 40, that is, the portion 150 nearest the panel 12 and the lever 48 is in contact with that portion vof the collar 40 which is nearertothe bifurcated boss 43. The portion of the collar 40 against which, thelever 48 resses is not eccentric.

' A cover p ate 57 holds the levers 45 and 48 and the spring'52 in place. The plate 57 is held by'means of a stud58 which passes throughthe plate 57 and into a boss 59 on the panel 12. j

On one side of the panel 1,2 is disposed a coin box 6() which is provided with a hinged door 61.. The portion of .the coin box 60. which is directly below the lower-'ends of the levers 45 and 48 is provided with an openin 1. 62,Y` through which the coin may-be droppe/ as hereinaftery described.

Directly below the plate 20is-disposed a coin return chute 63 which is secured to the side of the coin box 60 by means of flanges 64. 120

i hand of Figure lafThe coin C is also forced' to theleft hand of `Figure 1 and carries with vthe panel 12. Carried by the bar 66 isla flag 68 having thereon the word Empty or other indicia to indicate that the machine is empty. On one end of the bar 66 is a projection 69 whichV lies in the path of movement of a follow-weight in the package chute (not shown, but of construction shown in ourcopending application, Ser. No. 341,953), so thatwhen the lastpackage is vended the bar 66 and the fiag 68 are swung to the dotted line position shown in Figure 1. In order that the flag 68 may be seen from without, a window 7 Ois provided in a frame 7.1. The frame 71 is held by studs 72 to the front wall A of the vending machine. When the j indicating means is swung to the dotted line -position shown in Figure 1, one end of the bar 66 -is forced into the recess 18 in the plate 15. This not only tends to hold the bar166 in ahorizontal position but also forces a circular boss 73 on the forward face of the plate 15 into the coin opening 65 (as shown Figure 3), so that no coin 'can be inserted 1n the machine when Ait is empty.

The fianges 74 on the top of the front wall A andthe hook 75 on the bottom thereof are used, in conjunction with other means, to hold the front wall A in position on the machine. kThe letters C, W, and-S used in the drawings in'dicate coins, washers and slugs respectively.

* OPERATION (a) :iWLen' a proper 00in is inserted Vhen' a proper coin C is inserted in the Icoin opening it falls in a vertical line in l(see F igurev5) and is-caught and held be-l tween the lug 47 on the lever 45 and the fiange 49 on the lever 48. sary for theforegoing action by the coin C is momentary. v

The handle 42 is then turned clockwise which rotates the shaft 41. Since thelever .45 is against the thinnest portion `of" the eccentric collar 40,` when the shaft 41 is rotated the lever 45 is forced toward the left `it the lever 48 to the dotted line position shown in Figure 1.A As the lever .48 is moved the shoulder 50 thereon is moved from the path of'movement of the recess 51 on the collar 40 and the shaft 41 is free to rotate.

When the shaft 41 has made a lfull half turn the thickest part of the collar 4 0 is presented The coin C then rolls down thel The elapsed time neces-- to the lever 45. As the shaft 41 isA rotated until a full revolution of the collar 4()y has been made. Therefore, when the lever .45 reaches the dotted line position the gap between the levers 45 and 48 is large enou h to permit the coin C to drop through t e openino' 62 into the coin box 60. The rotation ofb full turn has been completed when the shoulder 50 on the lever 4 8 again engages the detent 51A on the collar 40 and the levers 45 and 481' 'fare in their normal positions. In the meantime, the projection 39 on the plate 15 has ridden over the successive teeth on the collar 40 and has returned to its original position. tion of the shaft 4l operates a goods dispensing means which is not shown and which forms no part of thisapplication.

. (b) when a washer a inserted j opening 65 it willfall between the plates 15 and .20 and the panel 12.' j As the washer W falls it'will strike the shoulder 37 on the latch 35. This will swing the latch 35' on its pivot 36l to the position shown in Figure 6 and the washer W will be caught o n the hook 38 of the latch 35. The shaft 41 is sufficiently free to permit a partial turn of the handle 42, so that the projection 39 on the-plate 15 will mount the first tooth on the collar 40. This will cause the plate 15 to move on its pivot the 'shaft/i1 then continues until aA It will'be understood that the rota- 16 and the lower part o'f the plate 15 will move away from the panel 12. rlhe spring 28 will be compressed and by reason of the pressure onnthe stud 29 the plate 20-will also move-away from the panel 12 but the plate 20 will not move as far as the plate 15 because the pin 30l in the flange 13 stops its progress4 after it has moved aslight distance. As the" plate 15 moves away from th'e panel 12 the latch 35 will be withdrawn from theslot 34' in the plate 20 and the washer W will be released from the hook 38. As the plate 20 moves away from the panel 12 the distance between the offset portion 20a of the plate 2O and the panel 12 will increase.- Therefore, when the washer W is released itwill not strike the offset portion 20a of the plate 2O V i but will fall between the plate 20 and the panel 1,2 into the coin return chute 63 and (c) When a slug s inserted J lwill be returned to the outside ofthe machine. l

If a slug S- or other improper coin is inmanner similar to a proper coin C. rl`he progress of the slug S will be impeded by striking the shoulder 37 of the latch 35 but will not be stopped. When the slug S reaches 5 a point adjacent the openings 24 it will be sto )ped and held by the magnet 21, as shown in igure 8. When the handle 42 is turned the plates and 20 will move away from the panel 12. Since the pin 30 in the flange 13 will stop the movement of the plate 20, the plate 15 will --niove further away from the panel 12. This will withdraw the ends 22 of the magnet 21 from the openings 24 in the plate and the sl-ug S will be released. Since the plate 20 is also moved away from the panel 12 the slug S will fall into the coin return chute 63 and will be returned to the outside of the machine.

When the mechanism is in normal position the projection- 39 on the plate l5 rests in a recess 76 between two of the teeth on the collar 40. Th

e recess 761s deeper than the other ?ng a latch plvoted Offcenter m one o the recesses between the several teeth on the collar 40. If the mechanism becomes jammed, 25 broken or inoperative in any position other than the normal position the projection 39 will either be in one of the recesses between the several teeth on the collar 40 or on top of one of the teeth. If the projection 39 is on top of one of the teeth on the collar 40 vthe plates 15 and 20 will be in the position shown 1n Figure 3. -The circular boss 73 on the plate 15 will obstruct the coin-opening 65 so that nocoinsmay be inserted'. If the projection 39 hes in any of the recesses between 4the teeth of the collar 40 other than the recess 76 the plates 15 and 2O will stilll be a suicient distance from the panel 12 to permit any Acoin which may be inserted in the coin opening 65 40 to drop through the-opening between the oil'- set portion 20a of the plate 20 and the panel 12.` so that it will be returned by means of the com return chute 63.
